For many litigators, sworn testimony today looks much different than it did two years ago. As the COVID-19 pandemic has required parties to limit travel and in-person proceedings, remote testimony for depositions, arbitrations and even trials has become the rule rather than the exception. With this transition, litigators have been confronted with unique circumstances and felt compelled to ask questions to confirm that the witness’s testimony is that of the witness, and only the witness. For example, is anyone else present in the room with the witness? Does the witness have any unauthorized lines of communication that could be used while the sworn testimony is proceeding? It has now become critical to ask a witness to swear under oath that there is no one else in the room with the witness and that no person is authorized to communicate with the witness during her or his testimony. Several recent decisions solidify this practice point and illustrate the consequences to litigants and lawyers when a witness surreptitiously communicates with others during the course of remote testimony.
